WATER BLADE NOZZLE.

Application filed April 26, 1921, Serial No. 464,636.

To all whom it may concern Be it known that I, HERMAN W. HIGLEY, acitizen of the United States, and resident of borough of Bronx, New Yorkcity, in the county of Bronx and State of New York,

have invented certain new and useful Improvements in Water BladeNozzles, of which the following is a specification.

The invention relates to water blade nozzles, by which term I mean todescribe a nozzle construction by which water may be delivered in aflat, comparatively thin stream, of uniform width and thickness, underpressure. I

The present invention maybe considered as in some respects animprovement upon my Patent 1362533, dated December 14th, 1920, for asanitary dish washer. Thepresent invention is intended to provide aneffective construction of the same character as that described in saidpatent, but which shall be particularly well adapted for use in avariety of fields.

I have found that the nozzle construction described in said patent maybe used very eifectively, particularlyv when made in larger sizes thanthose which were particularly contemplated in my said patent, for thepurposes of washing automobiles or spraying gardens and the like, andalso for washing streets and decks of vessels, etc. When nozzles ofsuflicient size are used the thin blade like stream under pressure maybe used very effectively for removing snow or rubbish from the streets,the form of the stream enabling the same to cut through obstacles veryeffectively.

The objects of my invention are the provision of improved devices of thecharacter described which may be operated efiiciently for the variouspurposes referred to, and which may be simple and practical tomanufacture. Other objectsof the invention comprise various combinationsof parts and details of construction as will be hereinafter more fullydescribed in the following specification. 7 g

The nozzle construction may be produced by stamping the partsthereoffrom sheet metal orby casting the same, but when the castingconstruction is used certain difiiculties are encountered; one of'theobjects of my invention is to overcome these difiiculties. My inventionalso comprises a construction which is efiectively strengthened" andbraced so that it may be used with comparatively large nozzles for thedelivery of a considerable body of water under pressure.

In order that the invention may be more clearly understood attention ishereby directed to the accompanied drawings, formmg part of thisapplication and illustrating one embodiment. of my invention. In thedrawings,

Fig. 1 represents a top plan view of a construction embodying myinvention:

Fig. 2' is in part a section taken on line 2-2 of Fig. 3, and in part aplan view of the device shown in Fig. 1;

Fig.3 is a section taken on line 33 of Fig. 1 ;v

Fig. 4 is an end view of the device; and Fig. 5 is a section taken online 55 of Fig. 3.

\ Referring to the drawings, the construction illustrated isparticularly adapted to be produced by a casting process. Theconstruction comprises a tubular, entrance portion 1 and a deliveryportion terminating at the outlet opening 2. The delivery portion of thedevice encloses what may be termed a water chamber 3, the side walls ,4and 5 of which are inclined toward each other, these walls convergingfrom the end of the tubular portion 1 to the outlet opening 2,

with inclinations which are preferably uniform. a

What I may term the end walls of water chamber 3 preferably diverge fora distance from the tubular portion 1' as is indicated at 6 and 7.Beyond the diverging portions,

the side walls 4 and 5 are likely to be deformed by the pressure of thewater rushment of the side walls 4 and 5 away from their normalpositions under the ,efiect of pressure. This means must be so formedingthrough the same. Accordingly I pref- I erably provide means forpreventing move-r and positioned as not to interfere with the form ofthe solid thin stream of water which is to be delivered from outlet 2.

I accomplish these objects by positioning a holding device some distanceback from the outlet 2. Preferably this takes the form of a rivet 9, orthe like, extending through the side walls i and 5 and provided withheads 10, 10, against the outer surfaces of walls 4 and 5. Alsopreferably a spacing member is positioned between walls 4 and 5, thisbeing any suitable device adjacent to, or in connection with, rivet 9for preventing movement of walls, 4 and 5 towards each other. PreferablyI use a spacer 11 in the form cf a sleeve surrounding the shank of rivet9, this sleeve having its end surfaces formed with suitable inclinationso that they will bear against the inner surfaces of walls 4 and 5. Byhaving rivet 9 and spacer 11 positioned some distance back from outlet2,the stream of water which is divided by spacer 11 will have ampleopportunity to come together again to form a solid stream at the outlet.

The device may be formed of two shells of pressed metal which may besecured to gether in the manner described in my said previous patent. Orthe device may be cast and this construction is preferable for someuses. V

When the deviceis cast the tubular portion 1 and the part of the waterchamber portion which is bounded at the ends of the chamber by thediverging surfaces 6 and 7, may be cast in one piece. The entire bladeof one of the sides of the water chamber, such as the side 5, may alsobe inte ral with this construction. That is to say, propose to cast inone piece the tubular portion 1 of the device, the partial water chamberportion bounded by the end walls 6 and 7 and by parts of the side walls4 and 5 and the forwardly extending blade portion 5 which extendsforwardly from the ends of the diverging walls 6 and 7 to the outletopening 2. T'his construction maybe cast about a single core which maybe withdrawn from the water chamber end of the construc tion after themetal has solidified.-

P It would, of course, not be possible to form the device complete as asingle casing about a single core, because the core could notv bewithdrawn.

Having provided the casting described above, the device may be completedby the provision of a blade member 4 which is complementary to the bladeportion 5 of the casting. This blade member 4- will have ber 4tmay bemounted in position by secur-, mg its end edges upon flanges 12 by anysuitable means such as rivets 13 which extend through openings let inflanges 12 and through corresponding openings in the end flanges ofblade member r Blade member 4 will abut at its rear edge against theforward edge of the partial side wall 4 of the casting, the junctionbetween these parts being indicated at 15. The two parts thus securedtogether may, of course, be welded or braced, or otherwise secured alongthe line 15, if desired. When the parts are so secured the upper, orside wall, of the chamber, indicated at L in Fig. 3, will be completed.

The tubular portion 1 may, of course, be provided with an internal screwthread 16 at its rear end for attachment to a hose, or the like, thisscrew thread being formed in the casting by any suitable process.

It should be understood that the invention is not strictly limited tothe details of construction which have been particularly de scribed, butis as broad as is indicated by the accompanying claims.
